By 1918, the railway gun was in use by nearly all the major combatants in World War II, though Germany was the major country with this powerful armament. But in 1934, practical work began on two new designs, one of them being the K5(E). The Leopold had an unconfirmed range of 11 miles and fired a pre-engraved projectile weighing approximately 550 pounds. It is fired from a turntable affording a 360 degree traverse. This plastic model is a highly-detailed, accurate representation of the military vehicle.
